I have an '89 Z28 with a 350 in it, and it still has the stock carburetor. I wanted some opinions on which aftermarket carburetor I should buy. I'm not looking for anything way too expensive, but for a reasonable price, I was wondering which performance carburetor would be the best for my car.

Thanks for the help,
Mason

 

It really depends on the rest of the setup, What cam and heads are you running? If it's stock a 570cfm holley street avenger or 600cfm edelbrock would be fine. If you plan on doing anything to it, or it's a mild street/strip motor a 670 holley street avenger or a 650cfm edelbrock would be perfect. I personally like the Holley's more then the edelbrock's but the choice is yours there.

Great, thanks. When I get around to buying it I'll probably go with the 670 Holley.

Thanks again.

 

I have the 670 on my 350 I love it, big difference over the edelbrock I had.

If you like tinkering with the carb for different conditionsm use an Edelbrock, which is basically a Carter AFB. If not, use a Holley. In both cases you want 750 cfm, and stay away from mechanical secondaries. Beyond that, just shop around. You can also consider a used one with a rebuild kit. You can buy this carb cleaner setup at an autoparts store. It's a bucket of cleaner with a sort of collander thing with a handle that lets you dunk the parts.

 

750 cfm?? Hope he has alot of cam and heads...

 

Don't get the 670, just get a nice 650 VS and put the quick spring change kit in - MUCH CHEAPER. And it's the same thing. Holley is making $$$ on the 670 thanks to their marketing department - NOT their engineering department as it's the same carb.

 

I got mine for 100 dollars
